Understanding the risk of unpaved roads on drinking water treatability by assessing sediment erosion across CanadaDownload
Forest harvesting, wildfire suppression, energy resource exploration, and recreation all require unpaved roads. As a result, many roads in drinking watersheds are potential sources of fine (<63 µm) sediment. Erosion of fine sediment threatens drinking water treatability as can be a source of...
This research determined if woody debris amendments facilitate land reclamation after oil sands mining. Specifically, it assessed if woody debris affects vegetation cover and richness, woody species survival and abundance, soil nutrients, temperature and water, microbial biomass carbon and...
Mountain pine beetle (Dendroctonus ponderosae; MPB) is a natural disturbance agent in western North America. Recently, MPB has been found beyond its historical habitats and threatening jack pine (Pinus banksiana) in western Canadian boreal forests. Jack pine is a fire-dependent species that...
Water is a resource crucial for the survival and growth of trees. Understanding water relations and how changes in water availability may affect the growth and survival of trees across spatial and temporal scales is critical to gain insights in the future of forests. Sap flow sensors allow...
Using a native plant-pathogen system as a model to investigate success of the invasive mountain pine beetle in jack pineDownload
Tree-infesting organisms have recently expanded their ranges into many novel habitats where they will not only interact with new host tree species, but also with a myriad of other organisms that also share these hosts. Understanding the major factors and mechanisms that mediate...
In this thesis I examined the impacts of variable retention harvesting on residual tree mortality and natural regeneration of white spruce [Picea glauca (Moench (Voss)] in northern Alberta. The VR was done in four overstory canopy compositions (ranging from deciduous dominated to conifer...
Variations in Size and Optical Properties of Dissolved Organic Matter During Mixing at Large River Confluences: Implications for Source Discrimination in the Boreal ZoneDownload
The functionality of dissolved organic matter (DOM) in natural waters depends on its size and composition. Identifying the sources and associated properties of DOM is vital to understand its effects on downstream ecosystems. River mixing has great potential to alter DOM quality, but its role in...
